How to transfer gta online cars to story mode?

The information we have about Grand Theft Auto Online only describes it as the online multiplayer component of Grand Theft Auto V and does not mention any mechanism for moving vehicles between the online and single‑player versions. Because the verified source does not cover this topic, we cannot provide a step‑by‑step method or confirm that such a feature exists. If you are looking for ways to use online vehicles in story mode, the evidence currently does not support that possibility.
